Magnetism typically arises from a conspiracy between Fermi statistics and repulsive Coulomb interactions that favors ground states with non-zero electron spin. As a result, controlling spin magnetism with electric fields---a longstanding technological goal---can be achieved only indirectly using spin orbit coupling. Here, we experimentally demonstrate direct electric field control of magnetic states in an orbital Chern insulator, a magnetic system in which non-trivial band topology favors long…

Orbital Chern Insulator and Quantum Phase Diagram of a Kagome Electron System with Half-Filled Flat Bands.

By further increasing J, it is found that the ferromagnetic topological phase is suppressed, which first becomes partially polarized and then enters a nonmagnetic phase with spin and charge nematicity.

Current-Driven Magnetization Reversal in Orbital Chern Insulators.

This work proposes a current-driven mechanism whereby reversal occurs along lines in the (current I, magnetic-field B) control parameter space with slope dI/dB=(e/h)MA_{M}(1-γ^{2})/γ, where M is the magnetization.

Strongly correlated Chern insulators in magic-angle twisted bilayer graphene

A local spectroscopic technique is introduced using a scanning tunnelling microscope to detect a sequence of topological insulators in MATBG with Chern numbers C  = ±1, ±2 and ±3, which form near filling factors of ±3, ±3 and ±1 electrons per moiré unit cell, respectively, and are stabilized by modest magnetic fields.

A scanning tunneling microscopy and spectroscopy study of gate-tunable twisted double bilayer graphene devices and self-consistent Hartree-Fock calculations suggest exchange-driven spontaneous symmetry breaking in the degenerate conduction flat band is the origin of the observed correlated state.

Tunable correlated Chern insulator and ferromagnetism in a moiré superlattice

The discovery of a C  = 2 Chern insulator at zero magnetic field should open up opportunities for discovering correlated topological states, possibly with topological excitations, in nearly flat and topologically nontrivial moiré minibands.

Evidence is presented that near three-quarters of the filling of the conduction miniband, these enhanced interactions drive the twisted bilayer graphene into a ferromagnetic state, and measurements suggest that the system may be an incipient Chern insulator.
